[Kolab-devel] [issue1562] KMail erroneously quotes RFC2231-encoded attachment filenames

[Frank Osterfeld]

New submission from Frank Osterfeld <frank at kdab.net>:

KMail quotes RFC2231-encoded attachment filenames:

Content-Type: text/plain;
  charset="us-ascii";
  name*="iso-8859-1''L%F6sung%2Etxt"
Content-Transfer-Encoding: 7bit
Content-Disposition: attachment;
	filename*="iso-8859-1''L%F6sung%2Etxt"

That's wrong, RFC2231 strings should go unquoted:

Content-Type: text/plain;
  charset="us-ascii";
  name*=iso-8859-1''L%F6sung%2Etxt
Content-Transfer-Encoding: 7bit
Content-Disposition: attachment;
	filename*=iso-8859-1''L%F6sung%2Etxt

These malformed strings cause the filename to be removed when using Toltec 
connector.
